SUPPORTING-REEL FOR WOUND COILS.

Application file'd luly 24, 1914.

To all whom it may concern Be it known that I, FRANKCRAWFORD, a citizenof the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Supporting-Reel for Wound Coils, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to avoid any retardation or drag on a coil when unwinding the same; toprovide an expansible core for a coil while being unwound; to provide simple and operatively manipulated means for securing a coil in a reel of the character described; and to provide a simple structure, the operation whereof serves automatically to exert a braking influence on the rotating structure when paying out the strand of which the coil is constructed.

Dmarz'ngs.Figure 1 is a plan view of a reel constructed and arranged in accordance with the present invention, showing in conjunction therewith a coil of wound wire; Fig. 2 is a vertical section taken on the line 22 in Fig. 1.

Descm'p2f2'0n.Asseen in the drawings, the reel proper has a basket-like structure, embodying a ring rim 7. The rim 7 is rigidly united to and supported upon the ends of vertical extensions 8 of radial arms 9. The inner ends of the arms 9 arerigidly connected to a central plate 10. The plate 10 is recessed to form sockets for the ends of the arms 9, which are clamped therein by a base plate 11, from which extend upward the standard arms 12.

The plates 10' and 11 are structurally united by screws 13, shown best in Fig. 1 of the drawings, and the arms 12 are integrally formed with a head 14, wherein is formed a socket 15, and extended from the top whereof are pivot supporting flanges 16. The

socket 15 is utilized to form a housing for the end of a pivot post 17 and a pivot ball 18, which is mounted upon said pivot post, or between the same and the inner end of the socket 15. The ball 18, when disposed as above described, constitutes a rolling pivot for the basket-like structure of the reel, permitting the same to move easily about the post 17 and the face plate 19 upon which said post is mounted. The spread of the Specification of Letters 'Patent.

Patented July 20, Serial noissassa plate '19 varies in correspondence with the service wherein the reel is employed. From the edge of the plate is extended a curved stripping arm 20, the upper end of which is provided with an inward extension 21, whereon is loosely mounted a guide ring 22. Through the guide ring22 the loose end 23 of the coil 24 is carried, to be guided thereby when unwound from the coil. The coils such as indicated by the numeral 24 are usually fiat, and are provided with a hollowor vacant center. Within this center are disposed framing-bars 25. The bars 25 are preferably constructed from strap metal, having at the lower end a twisted guide section 26, through a perforation in which, one of the arms 9 is passed. The perforation in the section 26'is sufficiently close to clamp on its respective arm when said bar is moved out of perpendicular'relation to the arm 9. The framing bars 25 are supported in the upright position by handle bars 27, each of which is united to one of the framing bars by a link 28. The-links 28 are pivoted one to each of the bars'by bolts 29, Each'of the links is clampedto one of the handle bars 27 by means of a wing nut 30. The handle bars 27 are each pivotally mounted upon one of the flanges 16 by a bolt 31. Each of the handle bars 27 is extended to overhang the rims 7 to prevent the coil 24 jumping from the arms 9, as above described.

0pemti0m- When employing a reel constructed and arranged as above described and as shown in the accompanying drawings, thecoil 24: is placed in the basket structure to'rest onthe arms 9 within the rims 7. Prior to placing the coil, the wing nuts 30 are loosened to perm'itthe free play of the links 28 and bars 25 and 27. The handle bars 27 are then engaged by the attendant, and raised to a vertical position above the pivot post 17. This operation draws the framing bars 25 toward the plate 10, the lower end of saidba rs sliding freely on the arms 9 with which they are connected. The coil 24 is then lifted into the basket of the reel, the arms 27 and parts connected therewith extending upward through the central opening in the coil. The coil is now adjusted by the attendant lowering the bars 27 until the framing bars 25 moveinto contactwith the inner edge of the coil 24:. In

the adjustment of the coil to the reel, the bars 27 facilitate the placement thereof in concentric relation to. the reel. The disproportionate height of the end of any one of the bars 27 signifies a proportionate displacement of the coil within the rim. The bars 25 having been adjusted to the coil, the wing nuts 30 are tightenedto hold the bars and 27 in their adjusted positions. The free end 23 of coil 2 L is now threaded through the guide ring 22, and the operation of unreeling the wire from the coil is proceeded with. If, in the operation, the handling of the wire after passing outward through the ring 22, is retarded, it immediately operates as a brake by the outermost one or more coils of wire spreading to contact with the extensions 8 of the basket frame, thereafter operating as a brake or check on the running of said frame.

"While I have herein described the invention in its application to coils of wire, it will be understood as being equally applicable in service, for unreeling coils of rope, twine, or other material.

Claims:

1. A reel having a basket portion embodying a plurality of radial arms, each providing perpendicular retaining extensions; a suspension structure for said basket portion, embodying an upraised bearing socket; a base plate; a pivot post rigidly mounted on said plate and extending above the bottom of said basket portion; a guide arm mounted on said base plate, infolding the side of said basket portion and extending inward thereover; and means provided on said arm for guiding material leaving said basket portion.

2. A reel having a basket portion embody ing a plurality of radial arms, each having a perpendicular retaining extension; a suspension structure for said basket portion, embodying an upraised bearing socket and a guide plate disposed at the lower end of said structure; a base plate, a pivot post rigidly mounted on said base plate and extending upward through said guide plate into said bearing socket; a guide arm mounted on said base plate, infolding the side of said basket portion and extending inward thereover; and means provided on said arm for guiding material leaving said basket portion.

3. A reel having a basket portion embody- Gopies of this patent may be obtained for ing a plurality of radial arms, each having a perpendicular retaining extension; a suspension structure for said basket portion, embodying an upraised bearing socket and a guide plate disposed at the lower end of said structure; a base plate, a pivot post rigidly mounted on said base plate and extending upward through said guide plate into said bearing socket; a rolling bearing member mounted upon said pivot post with in said socket bearing; a guide arm mounted on said base plate, iniolding the side of said basket portion and extending inward thereover; and means provided on said arm for guiding material leaving said basket portion.
